[0027] Reference Figures 1 to 4This utility model discloses a rotary printhead structure for a digital printing machine, including an inkjet holder 1 and inkjet heads 2, and a rotating disk 3 rotatably connected to the inkjet holder 1. The inkjet heads 2 are arranged in several rows on the rotating disk 3. The inkjet holder 1 is provided with a drive mechanism to drive the rotating disk 3 to rotate. In this application, the inkjet heads 2 can move laterally and rise and fall by the drive of a traveling mechanism 4. The paperboard is transported and moved by a conveying mechanism 5. Since the traveling mechanism 4 is prior art, its specific structure and principle are not described in detail. This application has a total of 16 inkjet heads 2, arranged in two parallel rows. In order to reduce weight, the inkjet holder 1 of this application is made of aluminum and has multiple weight-reducing holes.

[0028] The working principle is as follows: If the width of the cardboard is less than the length of the inkjet head 2 array, the drive mechanism can rotate the rotary disk 3, making the length direction of the inkjet head 2 array perpendicular to the moving direction of the cardboard. In this way, the inkjet head 2, once positioned, can cover the width of the cardboard without moving, thus increasing the printing speed and achieving high-efficiency printing. If the width of the cardboard is greater than the length of the inkjet head 2 array, the drive mechanism rotates the rotary disk 3, making the length direction of the inkjet head 2 array parallel to the moving direction of the cardboard, allowing printing to proceed in the original line-by-line inkjet method. Therefore, this structure enables different modes of printing, such as fixed or line-by-line inkjet printing, improving printing efficiency.

[0029] As shown in the figure, specifically, the bottom of the inkjet holder 1 is provided with a shaft hole 6, and the bottom of the rotating disk 3 is provided with a rotating shaft 7 that rotatably engages with the shaft hole 6.

[0030] The inkjet cartridge 1 has a bottom hole 8, the shaft hole 6 is disposed in the bottom hole 8, and the rotating disk 3 is disposed in the bottom hole 8. The inkjet cartridge 1 has a pressure plate 9, which can prevent the rotating disk 3 from coming out of the bottom hole 8. Through the above structure, it is ensured that the rotating disk 3 will not come out of the shaft hole 6 in the axial direction, while still allowing the rotating disk 3 to rotate.

[0031] As shown in the figure, the drive mechanism includes a drive motor 10, a drive gear 11 connected to the drive motor 10, and an arc-shaped rack 12 disposed on the rotating disk 3. The drive gear 11 meshes with the arc-shaped rack 12. Through the gear and rack transmission method, the structure is not only compact but also highly reliable.

[0032] As shown in the figure, the inkjet holder 1 is provided with a motor base 13, the drive motor 10 is fixed on the motor base 13, the rotating disk 3 is provided with an arc-shaped groove 14, and the arc-shaped rack 12 is fixed in the arc-shaped groove 14. The motor base 13 is provided to facilitate the installation of the drive motor 10, and the arc-shaped rack 12 is adopted as a separate part for easy manufacturing and processing. After processing, it is fixed to the rotating disk 3 with screws.

[0033] As shown in the figure, the rotary disk 3 is provided with a limiting block 15, and the inkjet holder 1 is provided with a limiting block 2 16 that can abut against the limiting block 15. In order to ensure the accuracy of the rotation angle, the limiting block 15 and the limiting block 2 16 are further preferably provided with a photoelectric sensor 17 on the limiting block 2 16, and a trigger piece (not shown in the figure) on the limiting block 15 that can trigger the photoelectric sensor 17. When the trigger piece triggers the photoelectric sensor 17, it proves that the rotation angle of the rotary disk 3 is just right. Through the redundant setting, the accuracy of the rotation angle of the rotary disk 3 can be fully guaranteed.

[0034] As shown in the figure, the rotating disk 3 has a groove 18, and the bottom surface of the groove 18 has an inkjet nozzle 19. The inkjet head 2 is installed in the groove 18. The rotating disk 3 has a middle plate 20, a top plate 21, and a support plate 22 supporting the middle plate 20 and the top plate 21. The middle plate 20 has an ink cartridge for supplying ink to the inkjet head 2, and the top plate 21 has electrical components. The reasonable arrangement of the above structure makes full use of the height space of the equipment, and the ink cartridge is above the inkjet head 2, making the ink supply smoother.

[0035] The above provides a detailed description of a rotary printhead structure for a digital printing machine according to embodiments of the present invention. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
